I have owned the travel-industry related domain names listed below for many years. These are all so-called premium dot-com domains which means the name already tells you what the website is all about.
Since I do enjoy my retirement life (after about 50 years in travel-related and other business matters) I decided to offer them for sale through www.Godaddy.com, the world's best and largest registrar.
Simply go to their website, search for the domain name that you like to buy and you will see a message like Congratulation, the domain is available and the price (unless someone else just bought it earlier and we had no time yet to update these listings below).
